中古音构拟已成定论,但上古音的构拟还存在诸多争议,作为湘语老派的娄底话较好地保存了中古音和上古音,作为重构上古音的一个重要支撑材料有着重大研究价值和意义,本文从娄底话的尖团音粗略分析上古音构拟推论中的一些问题,只为重构上古音提供诸多方言分析中的其中一种素材。 Although the ancient Chinese phonetic structure has become a definite conclusion, there are still many controversies about the construction of the ancient Chinese phonetics. The Loudi dialect, as the old Xiang dialect, has well preserved the ancient Chinese and the ancient Chinese phonograms, which is of great research value and significance as an important supporting material for reconstructing the ancient Chinese phonetics , This paper gives a rough analysis of some of the problems in the proposed inference of the ancient phonetic system from the apex tone of the Loudi dialect and provides only one of the many dialects in the analysis of ancient sounds.
